The Kurzweil SP1 is a stylish stage piano with a weighted 88-key hammer action keyboard and very user-friendly controls. It offers a choice of 16 tones, including a German D Artis Grand, electric pianos from the Kurzweil Forte SE, strings, woodwinds and brass from the Kurzweil PC-3. The SP1 features four individually adjustable effects (reverb, chorus, tremolo, delay) and a 3-band master EQ. It is possible to layer up to four sounds on top of each other, and there is also a split function. The high polyphony of 256 voices is high enough so that even when two people are playing the instrument at high speed, no fading note is swallowed. The low weight of just 12 kg makes the Kurzweil an ideal companion for your performance or for transporting to lessons.
In addition to the input for the power supply, there is a connection for a volume pedal and the included sustain pedal. Stereo outputs connect the instrument to a mixing console, audio interface or home stereo system. The stereo input is intended for connecting a smartphone or CD player, for example, and integrating the music from it into the exercises. The headphone output allows undisturbed playing and practising at any time of the day or night. Via the USB port, the SP1 can be connected to a computer to function as a master keyboard with music software (DAW). The MIDI inputs and outputs allow interaction with other MIDI equipment such as a sound expander or sequencer.
